How do I remove Fire Fox as the default setting on my eMac computer. I am unable to open some files I need to open with Fire Fox.


I receive a newsletter that has information I need. Since I chose Fire Fox as my default setting, I haven't been able to open it. It was so easy making Fire Fox my default, but not so easy to remove it. Jim Kennedy

You should at least install the latest Firefox 3.6.28 version for your Mac OS X 10.4 PPC computer instead of the current Firefox 3.6.18 version.
